To expect alien technology to be just a few decades ahead of ours is too incredible to be taken seriously. – Paul Davies
A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology. – Paul Davies
